Abstract: Apparatuses for expanding tubing and methods of use are provided herein. An exemplary process may include heating tubing to an expansion temperature, expanding the heated tubing within an expansion chamber by injecting a first fluid within the heated tubing to expand the heated tubing, and constraining expansion of the heated tubing within the expansion chamber by introducing a second fluid between an outer sidewall of the heated tubing and an inner sidewall of the expansion chamber.

Abstract: A continuous winding machine uses embedded controllers to monitor and control the winding settings in maximum speed applications. Power is supplied to the embedded controllers from a main power source through a rotary transformer. The control system can be operated either through wired connections to a local computer or processor, or through a wireless system, or a combination of both, depending on the specific application. The machine uses a high speed, closed loop tensioning system that includes the filament supply spools and the mandrel supply and takeup spools. The control system menu includes the various winding operations useful to each user. The control system menu can be accessed remotely via computer, or by telephone.

Abstract: A system of heat shrink lamination that uses one or more lamination chambers with forced flow of heated air from a central heating area. The central heating area includes at least one heating element. A fan situated at one end of the central heating area provides high speed air circulation by forcing the heated air down through hot air plenums in the lamination chambers. At the lower end of the lamination chambers, the hot air is returned through air flow ducts to the central heating area.

Abstract: A method of protecting a helmet shell and interrupting airflow around a helmet utilizing an air flow interrupter and helmet shell protector strip. The strip is constructed so that it can be applied to a helmet after manufacture of the helmet shell itself. The strip includes an attachment mechanism which is generally an adhesive backing. This allows the strip to be easily removably affixed to the helmet surface. The attachment mechanism must have sufficient strength so that the strip does not separate from the helmet surface during normal use.
